Dhaka-12 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh. Since 13 February, 2026, this constituency is represented by Bangladesh Jaamat-e-Islami candidate Saiful Alam.
The constituency encompasses Dhaka North City Corporation wards 24 through 27, as well as wards 35 and 36, integrating these areas within a single administrative and electoral boundary.
The constituency was created for the first general elections in newly independent Bangladesh, held in 1973.
Ahead of the 2008 general election, the Election Commission redrew constituency boundaries to reflect population changes revealed by the 2001 Bangladesh census. The 2008 redistricting added 7 new seats to the Dhaka metropolitan area, increasing the number of constituencies in the capital from 8 to 15, and altered the boundaries of the constituency.
Asaduzzaman Khan was elected unopposed in the 2014 General Election after opposition parties withdrew their candidacies in a boycott of the election.
